cnn-TRUCK To aill whom it may concern I Be it known that L RicH'ARD'WEBBBUR- NETT, residing'at the city of Montreal, Province of Quebec,Dominion of Canada, have invented certain new and vuseful Improve'-nients :in Car-'I`rucks;l and'I do hereby de clare that the following isa full, clear, and

exact description thereof.

My improved l truck lis vdesignedto take the-place ofvvwooden truckswherein'the side sills twist under 'what 'are considered normalf'sidethrusts of the car. Inthese wooden trucks it hasbeen necessary vto useVsuiicient metal to reinforcethe wood and'form the conventional compositewood and metal truck. This composite truckvis exceedii'igly heavy andbulky and of necessity composed of members which could'not be heldpermanently together' but --would use become loose. .This inventionprovides an used in the composite truck and,'a t the same time,dispensing with all the wood, the joints i between the various parts'being made by rivets, and, consequently, being lproof against looseningand atk thefsame time' aording the required-resistance to the the sidesills.

As heretofore constructed the brake .mechi i anism` is partly in the carbody and partly on the truck, the force being exerted on the car-bodyand transmitted to the mechanism on the truck with the followingdisadvantages: To apply the brakes the powerwas transmitted from thecylinder on the carbocly through a multiplicity of levers 'androds tothebrake lever on' the truck, this truck lever being in turn operativelyconnected to the brake beams, the power being utilized first in takingup the slack or lost motion in the different` connections of the leversand rods on the car body and then the lost motion between the car-bodyand truck and furthermore, the invention .practically eliminates thewell-known variation in' air brake piston'travel between the partsthereof when the car is standing and when in motion and causing all theindividual 4brake mechanisms at the different parts of wheels to beuniform.V Furthermore,"when the brakes were applied with the trucksrounding a curve the braking strain would be different from the brakingstrain when tlie trucks were traveling in a straight line,

v and the piston travel would also vary. These Specification of Lettersliatent.

' disadvantages areovercome by my invention and the truck has imparted.thereto maximum flexibility for the irregular relative vertical movementof the axle boxes or pedestals while affording the maximum resistance toall horizontal movements.

The invention consists .of the combination side sills and intersectingthe vertical planesA of the pedestals, pedestal-plates riveted to theopposite sides of the side-sills in juxtaposition with thel journals andcombined liners and spacers secured `between theped#` estal-plates. Thecoaction of this combination ef elements, owing to their mutualsupportingv and bracing qualities, constitutes a truck capable ofsustaining all normal strains with minimum material and ."'onsequentlyweight.

For full comprehension, however,-of `my invention reference must be hadto the ac-v coinpanying drawings forming 4a part of this specification'in which similar reference characters'` indicate l the same parts,` and.wherein Y -Figure 1 is a plan view of my improved truck partly inhorizontal sectional view.; Fig. 2 is a longitudinal sectional viewtaken on line F F Figj; Fig. 3 is a transverse vertical sectionalview-taken on lines B B andD D F ig'. 2; andvFig. 4 is a sectionalperspective view of one corner 0f the truck; and

Fig. 5 is a detail perspective view of one of the liner-spacers. l

The'side-sills as before mentioned consist of vchannels 2 2 spaced as at3 and rigidly united to a pair of spaced channels 5 set" back to. back.lThese members4 are united throughout their height by angle-brackets 4and at the top and bottom by plate metal plate gussets 6 extending overslightly less than one half ofthe length ofthe transoms and over thesidesills from a point at the junction lof the transom and at each sidethereof to -a point in vertical linewith the axis of the journals forwhich purpose theplates have extensions 7 and 70 along the side-sills 5and transoms being effected entirely through the flanges of the channelsby rivets 8; the structure thus formed has maximum strength ofconnection between'the transoms and side sills owing to the boxcrosssection. 10

Wide. surfacedv guides `for the journal boxes 10 and eificientlight-weight pedestals areV formed by inverted U-plates 12 with widenedtops 13,an'd cast-metal combined spacers and wearing members 14 and15..A

A pair of the platesa're riveted at the opposite sides of each end ofthe side-sills andv each has a cross-brace 16 riveted to and connectingthe lower ends of its legs, and the spacer-wearing-members are disposedtrans- 20 versely to the sills and connected by l'ong rivets 18 to thelegsof the pedestal-plates. The members consist. of side bars 17extending practically the full height of the space within the pedesta-lsand connected together in an`integral member bywebs, which, in the caseof the members at the ends of the truck,` extend throughout their heightas at 101 with transverse thickened portions 100 .cored or drilled forthe long rivets; while the webs 19 of the other members are slightlyless lthan half 'the height of their sidev bars to alto-'rd necessaryspace above them to accommodate the ends of thelequalizer bars 20. Thislatter construction enables either the equalizer bar to be removedwithout dismembering the balance of the truck otherwise than by thedisplacement of one of the members 14.

The truck frame is constructed as above to aii'ord the greatest carryingcapacity with the least material and weight, and', in addition, to carrythe air-brake mechanism. The latter comprises brake-cylinder 25,auxiliary reservo-ir 26, supplementary reservoir 27 and triple valve 28,to support which -a carrier frame is mounted on the truck consisting ofan angle-iron` crossv bar 30 resting upon and riveted to the innerchannels .of the side-sills which 'are extended as at 200 vfor supportedat their opposite ends uponsand riveted-to the crossbar 30 and-theadjacent transom. and intermediate angle-iron cross bars 34 and 35supported by and' riveted to the frame bars 32 and 33. This framecarries the cylinder andl reservoirs which are suitably braced, thetriple valve being oar. ried on the outer end of. the brake-cylinder.The piston rod 501s connected to lever 5.1 and through brake-rod 52 tolever 53, such levers being connected to the brake-beam 54. Below' thetransom is the spring plank this purpose and a series of preferablyvthree support the bolster to be presently described. 1'

The equalizing springs are indicated at 66. The goose-necks, 67, of theequalizing bars rest on the boxes, 10, contained in the pedes= tals.

71 are the axles. and V72"thevheels of the truck.

The brake hangers are shown at 73 and they are hung from headless hangerpins -74 of uniform diameter located in bearings '.75 exceeding Athem inlength and in which they are retained by cotter pin 76.

rlhe bearings 61 and 75 are cast in one piece with an attachment plate77 riveted to the gussets. The bearings consist of a sleeve 61 and asleeve 75, each blocked at one end by a portionbf the bearing forming apartial closure of that end which has a small hole 86; the hanger pins60 and 74 being slipped through the sleeves and upper ends of thehangers 58 and 73 into the cups, and 'held in place by eotter pins 90'passed through protruding ends of the sleeves and across the front ofthe hanger pins without entering' the latter. In order to receive theupper ends of the hangers the sleeves are divided into separate parts 61and 81 and and 85 all cast upon the same carrier plate as justmentioned. These bearings are located at right angles to the bolsterAwith their open ends in close proximity thereto, and chaiing plates 250are riveted to the bolster and extend downwardly between the latter andthe truck frame in position to be borne upon by the hanger pins if thecotters `are not in place, thus preventing accil dental displacement ofthevhanger pins and, j possibly, de'railment of. the r.truck by thehanger falling across one of the rails. To remove the hangers thecotters are first removed the chaing plates unfastened and the pinsknocked outl by a punch or drift in serted through lthe holes 86.

An advantage ofcasting the bearings in one piecewith' the plates 7.7.andattaching thev latter to the gussets is that the latter, anddconsequently the entire truck, is stifene The function of the gussets 6is to form .the side sills int'o box sections, and at the same .timeowing to their connection with the transoms act as lbraces againstdiagonal movement of the truck, and also act as an additional supportaugmentingv the angles 4 in their attachment of the transoms to the sidesills. Another function'of these gussets is the supporting'of thecastings 77 to whichv thebrake hanger 73 and 'spring hanger 58fareconnectedi l -57 swungby four. spring hangers, 58, con- 65 neeted attheir lower-ends to the spring-1 `l The advantageof my particularconstructionof pedestal is that as the parts thereof become defectivethey may be renewed without sacrificing any of the other parts.

The bolster consists of a pair of Z-bars 300A and 301 arranged withtheir upper iianges in apposition-.and braced and tied together by acenter plate 3D2-and side bearings of inverted U-form in cross-sectionwith flanges 303 extending transversely to the-bolster;

' the bottom flanges being united by a center tie-plate 304 andcombination tie-plates and spring-seats 305. The springs are supportedupon spring-seats 306 resting upon the4 spring-plank. All the parts ofthisbolster are riveted together.' A
